Key Fluid Physics

The non-premixed Sandia D flame is an example of a flame in the flamelet regime in which the Kolmogorov scale is significantly larger than the scales characteristic for the combustion process. In this not demanding test case the models based on flamelet assumption should lead to good agreement with experimental data as was shown in the Evaluation section, especially in the region of developed flame. However, more discrepancies were observed in the near field were only mixing of fuel and oxidizer is considered.
